Revvity, has announced the launch of the EURORealTime™ APOE assay, an in-vitro diagnostic test now available in European countries that accept the CE mark. This new test offers accurate genotyping of the APOE gene, which plays a critical role in assessing a patient’s risk for side effects before beginning anti-amyloid (beta) therapy for Alzheimer's disease.
“With the advent of disease-modifying drugs for Alzheimer’s, a new era of therapy has emerged. However, patients with certain forms of the APOE gene are at significant risk of developing potentially life-threatening side effects known as ARIA (amyloid-related imaging abnormalities), which can cause brain edema or microbleeds,” said Dr. Lars Komorowski, Chief Scientific Officer of EUROIMMUN. “Determining a patient’s APOE genotype before starting therapy is crucial to evaluating their individual risk.”
The real-time EURORealTime APOE PCR test simultaneously detects the three most common APOE forms—E2, E3, and E4. Carriers of the E4 variant are at the highest risk of ARIA during treatment. With the new test, only one reaction is required from a single blood sample to determine the APOE genotype. The assay can be automated to varying degrees using Revvity’s platforms, including the EUROIMMUN PreNAT II™ and chemagic™ 360, with results processed using EURORealTime analysis software.
This APOE genotyping test will provide clinicians with valuable insights, enabling a more personalized and risk-assessed approach to Alzheimer's treatment.
